246. Principle of arc spraying rapid tooling
Basic principles: the two are connected to the positive and negative DC power supply for self-consumption of the metal wire of the electrode generated by the end of the metal wire arc melting; behind the arc in the nozzle injection speed, high pressure air from the molten metal and atomized into particles at high speed [2] the impact the substrate surface, flattening them to form a smooth, dense, low porosity of the metal coating layer. Process: Preparation of release agent prototype brushing ---- ---- ---- metal spray filler placed reinforcements pouring Stripping ---- ---- surface polishing.
Rapid prototyping technology has been widely used conceptual model of rapid manufacturing, rapid test model making, rapid tooling and rapid functional parts manufacturing and other fields.
We are constantly looking for new products in order to grow our business and Invention Home has enabled us to streamline that process much more quickly.
